Answer:
Cumulus and cumulonimbus clouds are typically associated with warm fronts, which occur when warm air moves into an area of cooler air. As the warm air rises, it cools and condenses, forming clouds. Cumulus clouds are often associated with fair weather, while cumulonimbus clouds can produce thunderstorms and other severe weather. Cold fronts, occluded fronts, and stationary fronts can also produce clouds, but they are typically associated with different types of cloud formations.
